Under the new CBA, teams are eligible to receive a disabled player exception worth the lesser of 50% of the injured player's salary or the amount of the non-taxpayer mid-level exception. In this case, half of Arthur's salary works out to just over $1MM, so Wallace doesn't have much flexibility.

"I can't say for certain if we'll use it," Wallace said. "It's fairly small as exceptions go. It's just one more piece to have. When you look at the restrictions around it, the probability is we won't use it."

The Grizzlies, who have until March 5th to use the exception, can only use it to trade for a player in the final year of his contract.
